Method for preventing end part of antiroll torsion bar from galvanic corrosion

Abstract

The invention discloses a method for preventing an end part of an antiroll torsion bar from galvanic corrosion. The method comprises the following steps: spraying a coating on the outer peripheral surface of a torsion bar end part such that the coating is located between the torsion bar end part and a torsion bar bearing and a main sealing ring is arranged between the end part of an antiroll torsion bar and an end surface of a torsion rod bearing; during assembly, firstly enabling the main sealing ring to sleeve the torsion bar end surface of the torsion bar, enabling the torsion bar end partto insert into the torsion bar bearing, utilizing the end surface of the torsion bar bearing to compact and attach the main sealing ring onto the torsion bar end surface during an insertion process such that a sealed attachment surface is formed on the end surface of the torsion bar, thereby preventing galvanic corrosion. During an application process, rusting corrosion at the torsion rod end partis avoided. The rejection rate of an antiroll torsion bar device is reduced. The cost of overhaul is lowered. Additionally, limits of foreign technology are removed. The maintenance market is automatically mastered.

Description

technical field [0001] The invention relates to a method for preventing galvanic corrosion, in particular to a method for preventing galvanic corrosion at the end of an anti-rolling torsion bar. Background technique [0002] When a rail vehicle passes through curves and turnouts at high speed or stops on a curve with superelevation, the roll increases significantly, and the load on one side of the wheel is reduced. When encountering strong lateral winds, it may even overturn and become unstable, reducing safety. It is necessary to increase the roll stiffness of the vehicle to limit its roll angle, but it cannot affect the vibration characteristics of the vehicle such as ups and downs, yaw, shake head, telescopic and nod. [0003] The anti-roll torsion bar component device is installed on the rail transit vehicle. When the rail vehicle is rolling, the torsion bar shaft is twisted and deformed, and together with other components, it provides the roll stiffness required for the...
